Customer Reviews (4.4 / 5 · 5 reviews)

Aurora ★★★★★

These bolts are seriously heavy-duty; the 10.9 grade steel feels rock solid when you're torquing them down. The partial threading gave me just the right grip length for sandwiching two steel plates, and the zinc coating looks factory-fresh.

Chloe X. ★★★★★

The hex head grabbed onto my socket wrench perfectly, and the zinc plating looks clean and durable. These 180mm screws fit my machinery jig without any wobble, so I’m glad I got the partially threaded version.

Stella P. ★★★★★

Finally, a bolt that doesn’t strip when you look at it — the class 10.9 steel is solid, and the zinc plating held up through a few rainy days on the job. Threads are clean and the partial threading makes alignment a breeze. Just what I needed for a heavy equipment mount.
